Configuration and Set up Information

Variable Speed Errors
Because the detector can only work within a pre-determined speed range it is
possible for the belt speed to move outside the limit of reliable operation of the
machine. In these cases, speed-logging problems can be selected in the
configuration menu that will generate either speed too slow or speed too fast run
errors. The fitted filter resistor pack will require changing to a pack which
encompasses both the slowest and fastest conveyor speeds required if
possible. Refer to “Belt Speed” section of this section for available choices.
NOTE
Ensure that JP7 on the Control Board has the link fitted between 1 - 2.
(Failure to do so will render the calibration routines inoperative).
HEAD POWER
The detector is able to automatically adjust its sensitivity in response to product
effect therefore enabling the best calibration and subsequent metal
contamination sensitivity to be set. This is achieved by the use of electronic
switches controlled by the software and hardware fitted on the control board.
The actual switches and the functions controlled are part of the search head
electronics board located behind the removable end plate on every detector.
The setting of these switches is decided by the Full calibration cycle carried out
before running a product for the first time. But manual selection via the “Manual
setup” menu position is allowed, but great care must be exercised before
manual intervention as false rejects or reduced sensitivities to metal
contamination may result.
The detector has 4 switches referred too individually as Control lines (Ctrl) but
collectively as “Head Power”.
Following is a table detailing the switch settings.
